EXA Infrastructure Removes Major European Network Bottleneck with Marseille–Paris Route Upgrade

London, October 20th 2025 – EXA Infrastructure, the largest dedicated digital infrastructure platform connecting Europe and North America, today announced a major investment to enhance network diversity and capacity between Marseille and Paris, addressing one of Europe’s critical connectivity constraints.

For more than 15 years, the Marseille–Paris corridor has represented a key bottleneck for data traffic moving between southern Europe, North Africa, and the rest of the continent. EXA Infrastructure’s latest investment removes this long-standing constraint.

After being the first operator to provide new low-loss G.652D fibre between Paris and Marseille in 2024, EXA Infrastructure is now increasing the fiber count on that route due to unprecedented demand for access to subsea cables. At the same time, EXA is delivering enhanced route diversity between those critical hubs with a new and fully geographically diverse Paris–Dijon–Marseille route, improving resilience for customers across the region. These two investments combine to provide a unique proposition of two fully diversified, low-latency routes with scalable modern fibre serving this critical corridor.

This announcement follows EXA’s recent €1.3 billion refinancing, which has strengthened the company’s capital structure and enabled accelerated investment in its pan-European network. It demonstrates how EXA is deploying new capital to remove historic bottlenecks and expand the capacity of critical digital routes that underpin Europe’s data economy.

“Enhancing network diversity and removing long-standing constraints like the Marseille–Paris corridor is central to our mission of delivering a more resilient and scalable digital infrastructure for Europe,” said Steve Roberts, SVP Network Investments and Products at EXA Infrastructure. “This investment directly supports the needs of hyperscalers, AI and HPC providers, and enterprise customers who depend on high-performance, low-latency connectivity.”

The Marseille–Paris routes form part of EXA’s broader strategy to remove major European network bottlenecks, strengthen connectivity between key hubs, and support growing demand from data-intensive industries. It further reinforces EXA’s position as the leader in pan-European connectivity and infrastructure innovation.
